BinCIuding'fits fiange" The novel elbow sectio x 5 's a ran to tur or wiiel'be s et 'n a I 0 and rollers 20; "and this section 28 is made in two-parts, namely 25 nd a pat '2 to fa c'ej relatio'njbyiU-cliip clips" receivesibetwe' n theftw side ofgthe edgesfgoffth e 't o'fian' c ,7 I loolts'ii'llsee'lii gQf;rOne'leg rear; lip he s 31'threaued eret rougn so hatjeacn bolt','bnly engages thelface of :tne 1.fian;g adjacenti'to this leg of j'the" clip Thusithei'iseetiqns; or: parts" 251- and 32 ofthe elbow 28 are free;tolturh-.or,swivel with respect to each'lother for ny an ei rgaa, J'ustment desired-fromtherear of truck I 4.

The t-P t t esco i S Q Q SrZlSis mount- 1 ed around the part 32 of the elbow 28, and is larger in diameter for this purpose, while section 30 is of larger diameter than 29 and is mounted around the section 29. Also, the section 3| is similarly larger than section 30 and is mounted around section 30.

Thus the sections may telescope from the ex- 3 tended positions shown to a folded position on and around the part 32 of the elbow 28, if desired. Near the open end of the part 32 within its bore, the part is pushed out to form an annular bead 40. The outer diameter of the bead 40 slides inside of the section 29 and is prevented from sliding back out of the end of section 29 by means of an annular bead 4| formed in the end of section 29, which is pushed in from the outer side of the section, so as to serve as a stop against a which the head 40 strikes when the sections are extended. a

Each section 29-30 and 3fl3i are similarly beaded as shown at 40 and 4|, ior cooperatively contacting each other in extended positions.

In order to hold the telescopic sections in their extended positions during use of the chute to unload coal or the like, there is mounted across the valley defined from each bead 4| an internally threaded nut 42. The nut 42maybe soldered to the outer ends of each section as shown at-43, in Figure 5. Threadably adjustable through the nut 42 and a threaded aperture inthe bead 4|, is a set screw or L-headed bolt44. Thus when the sections are extended the bolt 44 may be turned, so that its end 45 presses against the outer surface of the adjacent smaller inner section.

The general, operation of the device should be :apparent from the foregoing description; briefly reviewing the same, the plate ill is bolted over the opening it in the end or tail gate of the dump truck I4. The truck is backed up as close as possible to an entrance opening, not shown, for receiving the material discharged from the truck through the chute. Assuming that the entrance opening is so placed that it is oil to the side of the rear end of the truck, then section 25 and portion 32 may be turned until the telescopic section 29, 30 and 3 I can be inserted toward and into the opening. 1

Once that thelastsection 3| has been inserted in the entrance opening, then the elbow parts 25 and 32 may be locked to their present adjusted position by means of bolts 3l; and the portion 25, which carries flange 23 may be latched against turning by an L-shaped bolt 46, see Fig. 7.

The bolt 46 is mounted in a bracket 41 soldered to the outerv side of-flange 23, and has a fixed washer 48 nearjits latchjend adapted to limit the extent to which the bolt .46 penetrates through the respective aligned openings 59 and in the flange'23 and the plate ID. The bolt 46 is normally forced into engagement within the openings 50 and 5! by a spring 52 coiled between the washer 48 and the bracket 41. Thus to adjust the entire chute, elbow and all, it is only.

and advantages of the present invention should be apparent and although one embodiment has been illustrated and described in detail, it is to be expressly understood that various changes in" construction are intended to be included within the scope of the present invention. To determine the scope of the present invention reference should be had to the appended claims,

i vehicle, releasable securing elements coupling the two elbow parts together for changing the angularrelation of the parts, a plate secured to the rear wall of the dump vehicle, a flange carried by one part of said elbow, studs extending from the plate, and rollers journalled on said studs, said flange riding on said rollers for turning thereon, whereby the entire chute maybe turned on this connection when said elbow parts are locked together by said securing elements.

2.v A chute attachment for a vehicle having a wall provided with a discharge opening, comprising a centrally apertured plate member adapted to be secured to said wall over said discharge opening, a chute elbow havin two angularly related sections, one of said sections having at one end an outstanding encircling track flange, the said end of the said one section being positioned concentric with the aperture of the plate, means carried by the plate providing a plurality of rollers encircling said flange whereby said pipe elbow may be rotated with respect to the apertured plate, means for coupling the flange to the apertured plate to secure the elbow against turning, and a pipe comprising a plurality of telescopically joined sections, an end of one of said sections being telescopically connected with the other section of the elbow.

3. A chute construction of the character stated in claim 2, wherein said roller means comprises headed studs secured to the apertured plate, a disk member rotatably mounted on the stud and between which and the adjacent apertured plate the-said flange positions, and a spacer collar upon each stud and interposed between the apertured plate and the roller disk.

4. A chute construction of the character stated in claim 2, wherein each of said elbow sections carries an'integral encircling flange, the flanges of the two elbow sections being in abutting relation, substantially U-shaped elements straddling the said flanges, and a binding screw carried by one side of each U-shaped element for engagement with the adjacent flange to effect the binding together of the two flanges.
